Dynamic Circuit Grouping for Telecommunication Reset Overload

Find Innovative SolutionsGenerate Solutions

Solution Overview

Problem

In multi-processor based telecommunications networks, node failures lead to a high number of reset messages being generated, overwhelming the communication interface due to the inability to reset non-consecutive circuits using Circuit Group Reset messages, resulting in increased signaling and potential overload.

Innovation Solution

Introducing a group identity dynamically assigned to each circuit during call setup, allowing for the communication of this identity between nodes, enabling efficient resetting of only busy circuits matching the stored group identity, thereby reducing the number of reset messages needed.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If individual reset messages are sent for each non-consecutive circuit in multi-processor nodes, then all circuits can be reset, but the number of reset messages increases tremendously, overloading the receiving node

Engineering Contradiction:

Improvecircuit reset completenessVSAvoidmessage overload

Core Design Contradiction:

ReliabilityVSObject-generated harmful factors

Solution Approach 1:

The patent segments the large set of circuits into multiple smaller groups, each identified by a unique group identifier. When a reset is needed, only the group identifier is transmitted instead of individual circuit identifiers, dramatically reducing message size and enabling efficient reset of multiple non-consecutive circuits in a single message

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The patent introduces a new dimension of grouping by adding group identifiers that categorize circuits into manageable sets. This dimensional addition transforms the reset mechanism from circuit-by-circuit identification to group-based identification, allowing bulk resets without enumerating each circuit

Inventive Principle:

Principle #17Another dimension (Dimensionality change)

2Productivity

If Circuit Group Reset messages are used for consecutive circuits, then the number of reset messages is reduced, but non-consecutive circuits cannot be reset efficiently

Engineering Contradiction:

Improvereset message efficiencyVSAvoidcircuit grouping flexibility

Core Design Contradiction:

ProductivityVSAdaptability or versatility

Solution Approach 1:

The patent makes circuit grouping dynamic by allowing group identifiers to be assigned flexibly to any set of circuits regardless of their consecutiveness. Groups can be created, modified, and deleted dynamically to match changing network conditions and failure scenarios, enabling both consecutive and non-consecutive circuit resets efficiently

Inventive Principle:

Principle #15Dynamics

3Reliability

If all circuits are reset upon node failure, then reliability is improved, but signaling overhead increases significantly

Engineering Contradiction:

Improvenode failure recoveryVSAvoidsignaling overhead

Core Design Contradiction:

ReliabilityVSLoss of information

Solution Approach 1:

The patent performs preliminary grouping of circuits into identified sets before failures occur. When a failure happens, the pre-established group identifiers enable immediate targeted resets of only the affected circuit groups, avoiding the need to reset all circuits and significantly reducing signaling overhead while maintaining reliability

Inventive Principle:

Principle #10Preliminary action

AI summary

A method of communicating from a first node of a first telecommunications network towards a second node of a second telecommunications network is executed by the first node and comprises dynamically assigning (102) a group identifier to at least one circuit usable by the first node during communicating and sending (104) the group identifier towards the second node.
